1994 rodeo automatic, V6 starter relay problem

Postby tradewinns » Wed May 17, 2017 3:14 pm

now this has me buffaloed. (not that it takes all that much) i have the described rodeo. it is in a no start/no crank condition. removed the relay and checked for the click, it clicked. then went to check for voltage on the connectors the relay plugs into. (the relay i took out is a 5 prong relay) the actual wire that would connect to what should be the 87A terminal was missing from the slot. figured some jack leg mechanic (probably me) pushed it out an into the box when checking voltage, as i was trying to do. opened box and there is no wire there, broken, cut, hanging around--nothing. could someone have removed the wire entirely because they could by pass something and still operate the rodeo? and if there is a wire what color should i be looking for? i am definitely over my head on this one.

any help would be appreciated.

Typically Pin 87A is the Normally Closed contact (NC). Pin 30 is swinger and Pin 87 is the Normally Open contact (NO).

have you ever heard of someone removing a wire and it functioning? i do not see how it could work.

thanks, i've copied the drawings. if i find the wire somewhere, i'll need it.

According to the schematic the 87A (NC) Pin is not used so only 4 pins are connected.
When the transmission Range Mode Switch is placed in Park/Neutral the diode in series with the relay coil conducts causing the relay to energize and connect Pin 30 to Pin 87 (NO).

now that makes sense, thanks. i'm going to close that box up and move on. as i'm just getting started on this problem i'll most likely have dozens of more questions, so check on me every once and awhile,

again thanks

You have 12v at the starter when you turn the key?
Last year my starter went bad (intermittently) I wasted a lot of time tracing the circuit starting at the ign switch, had I started at the starter end I would have saved some time.
Lucky I have a 2wd manual, r&r was less than an hour even taking my time. 4x4... uh oh.
